Medicinal evolution and modern research progress on Mume Fructus / 中国中药杂志

Prunus mume is an edible and medicinal material, and Mume Fructus is its processed product, which was first recorded in Shennong's Classic of Materia Medica(Shen Nong Ben Cao Jing). It is an effective drug for stopping diarrhea with astringents and promoting fluid production to quiet ascaris. By consulting the ancient herbal works of the past dynasties, modern codes, and other rela-ted literature, this paper sorted out the medicinal evolution of Mume Fructus, examined the ancient efficacy of Mume Fructus and the main indications, and summarized the inclusion of Mume Fructus in national and provincial standards. It is recorded in the ancient herbal works of the past dynasties that Mume Fructus can be processed by various methods such as roasting, stir-frying or micro-frying, stir-frying with charcoal, single steaming, steaming with wine, and steaming after soaking in wine or vinegar, and prepared into pills, powders, and ointments, which are used in the treatment of fatigue, diabetes, malaria, dysentery, ascariasis, and other diseases. Mume Fructus has been included in nine editions of Chinese Pharmacopoeia and 19 provincial and municipal preparation specifications. The processing method of Mume Fructus is determined, namely, clean P. mume should be softened by moistening in water or steaming and pitted. By reviewing the effects of processing on its chemical composition, pharmacological effects, and its modern clinical application, this paper identified the following issues. The ancient application methods of Mume Fructus are diverse but less commonly used in modern times, there is a lack of standardized research on the processing, and the research on the changes caused by the difference in Mume Fructus before and after processing is not deep. Therefore, it is necessary to further investigate the change pattern of its chemical composition before and after processing and its correlation between its medicinal activity to standardize the processing technology and provide a solid basis for the use of Mume Fructus in parts and its quality control.

Detection of SALL4 mRNA expression in leukemia by real-time fluorescent quantitative PCR / 中国实验血液学杂志

This study was purposed to establish a real-time fluorescent quantitative PCR (FQ-PCR) for quantifying SALL4 mRNA and to investigate its expression in different types of leukemia patients. SALL4 mRNA expression were measured in 60 leukemia patients of different periods and 10 normal controls sequentially by FQ-PCR. The results showed that the expression of SALL4 mRNA in de novo leukemia patients and relapsed patients was higher than that in controls (P < 0.05), which was significantly decreased at complete remission (CR). In relapsed patients, the expression of SALL4 mRNA increased slightly higher than that in de novo leukemia group, but the difference was not statistically significant (P > 0.05). However, the expression of SALL4 mRNA was low in CLL, T-ALL and AML-M3. The expression pattern of BMI-1 was same as SALL4, and the expression of BMI-1 positively correlated with that of SALL4 in leukemia (r = 0.825, P < 0.01). It is concluded that the detection of SALL4 gene expression in acute and chronic leukemia by real-time gTR-PCR displays high sensitivity and specificity. SALL4 gene may be one of indicators for monitoring the therapeutic outcome of partial leukemia and minimal residual disease.

Evaluation of coronary heart disease risks in patients with psoriasis / 中华皮肤科杂志

Objective To estimate the 10-year risk of coronary heart disease in patients with psoriasis,and to determine whether the risk profile is affected by disease duration,family history and clinical types of psoriasis.Methods Data were pooled from 322 inpatients with psoriasis and 297 inpatients with other skin diseases (151 cases of acute urticaria,33 drug eruption,113 herpes zoster) from December 2008 to December 2010 in the Department of Dermatology,West China Hospital of Sichuan University.Risks of coronary heart disease were estimated by using the Framingham risk score algorithm.Wilcoxon rank test,Kruskal-Wallis test and chi-square tests were used to evaluate the differences in risks and risk factors between the patients with psoriasis and controls.Results As far as the Framingham 10-year risk score was concerned,the difference was statistically significant between the patients with psoriasis and the control population (6％ vs.4％,Z =4.342,P =0.000),as well as between patients with different clinical types of psoriasis (6％ for psoriasis vulgaris vs.4％ for pustular psoriasis vs.7％ for psoriasis arthropathica vs.7％ for erythroderma psoriaticum,H =8.484,P ＜ 0.05),but was insignificant between patients with familial and sporadic psoriasis (6％ vs.6％,Z =0.406,P ＞ 0.05 ).No correlation was observed between the Framingham 10-year risk and psoriasis duration (P ＞ 0.05 ).Conclusions Increased risks of coronary heart disease exist in patients with psoriasis compared with those with acute urticaria,drug eruption or hepers zoster,and in patients with psoriasis arthropathica or erythroderma psoriaticum compared with those with pustular psoriasis.The Framingham 10-year risk of coronary heart disease is uncorrelated with disease duration and unaffected by family history of psoriasis.

Effects of CGRP on the E-cadherin expression in human bronchial epithelial cells / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To discuss the effect of calcitonin gene-related peptides (CGRP) on epithelial cadherin (E-cd) expression in human bronchial epithelial cells (HBECs) in vitro.</p><p><b>METHODS</b>The effect of CGRP on E-cd protein and mRNA expression in both normal and O3-challenged HBECs were determined by immunocytochemistry and RT-PCR. The signal transduction pathways of CGRP were observed by using protein kinase C(PKC) inhibitor (H-7), calmodulin(CaM) inhibitor (W-7) and PKA inhibitor (H-89).</p><p><b>RESULTS</b>CGRP increased E-cd mRNA and protein expressions of normal and O3-challenged HBECs in a dose-dependent manner. CGRP had no effect on cytoplasm E-cd expression. Pre-treatment with H-89, H-7 and W-7, the up-regulatory effect of CGRP on E-cd expression was partly abolished.</p><p><b>CONCLUSION</b>CGRP increased in cytomembrane E-cd expression of normal and O3-challenged HBECs in a dose-dependent manner. E-cd expression on HBECs was strengthened by CGRP via PKA, PKC and CaM pathways.</p>

Laparoscopic partial gastrectomy: Analysis of 18 procedures / 中南大学学报(医学版)

OBJECTIVE@#To explore the laparoscopic partial gastrectomy and the indications.@*METHODS@#Eighteen patients who underwent laparoscopic partial gastrectomy from August 2005 to May 2006 were analyzed retrospectively.@*RESULTS@#Sixteen patients (including 6 with gastric cancer, 9 with duodenal ulcer, and 1 with gastric multiple polyps) underwent laparoscopic partial gastrectomy. The other two patients underwent an open surgical procedure (1 patient with the tumor size large than 6 cm, and the other patient with bleeding after loosening one clip). The rate of intraoperative subcutaneous emphysema was 5.88% (1/17), and no death occurred. The operation time was (285+/-30)min on average, the estimated blood loss was (130+/-50)mL, and the hospitalization was (11+/-4)d. One case of obstruction of distal loop happened after the surgery, and the rate was 6.25% (1/16). The patients were followed up for 1 approximately 9 months postoperatively. Trocar puncture-site metastases occurred in one patient.@*CONCLUSION@#Laparoscopic partial gastrectomy is safe and feasible with skillful laparoscopic technique and with restricted indications, and the surgical outcome may be similar to that of the open surgery.

Objective To assess the effect of resident training in clinical skills on SARS prevention and treatment. Methods A survey was conducted by means of questionnaires on 101 residents of the authors' hospital who were at the forefront of the fight against SARS. Results Training in clinical skills assisted the residents to various degrees in SARS prevention and treatment. 100% of the residents surveyed held that the training was helpful, beneficial and assisted them in solving problems. Conclusion Training in clinical skills, which rendered the residents proficient in basic skills and more capable of clinical application of the skills, also enhanced their ability to handle emergent events in SARS prevention and treatment.
